Abstract: Apparatus for automating a high volume instrument (HVI) used for the classification of all Upland and American Pima cotton, including determining trash and color. A sub-sample delivery tube sub-system and a sample drum air chamber sub-system allow the HVI to receive sub-samples from an automated cotton system. A delivery tube, with an air dissipater, delivers the automated sub-sample to the HVI sample drum while an air chamber below the sample drum applies a negative air pressure to the drum. A sub-sample air-knife extraction sub-system and an autoMIC transfer tube assist sub-system allow the HVI to release automated sub-samples after the sample drum in the HVI has completed its operations on the sub-sample. An air-knife applies air jets to the sample plate of the HVI sample drum to release the sub-sample. As the sub-sample leaves the drum an air jet is actuated to push the sub-sample along a transfer tube.

Abstract: Provided is a method for controlling a zero sequence voltage of a voltage source converter. When an alternating current system ground fault occurs, a zero sequence voltage at an alternating current (AC) side or a zero sequence voltage at a direct current (DC) side of a converter is detected. If the detected zero sequence voltage is greater than a set value V0ref, a DC side voltage of the converter can be increased to a set value Udc0, thereby generating an appropriate reference wave at the AC side of the converter to match an AC voltage, and accordingly controlling overmodulation of a reference wave at a faulty station to suppress fluctuation of a DC voltage.
